The new treatment combines omeprazole, amoxicillin, clarithromycin, and furazolidone, with only 31.4% of patients experiencing adverse effects.
HBV infection induces increased steady state of ATR protein and phosphorylation of downstream targets including Chk1, p53, and H2AX. The level of Mre11 and p21 were reduced after HBV-positive serum addition. This suggests that HBV escapes the consequences of activation of the DNA damage checkpoint by degradation of checkpoint proteins.
